Hi Felix, thanks for the awesome patch and great progress on the 802.11n! I just tried out your patch version 3, and got the following results. The results are an average of 10 different iperf runs, Throughputs are in Mbits/sec AP: dir-615 (settings: 802.11n mode only, Auto 20/40 Mhz). This AP does not seem to allow me to set 40Mhz only Node interfaces: D-Link DWA-556 Xtreme N PC scenario 1: node 1 to node 2 node1-----wireless_link-----AP-----wireless_link-----node2 802.11n Felix's Minstrel Avg Transfer= 38.6 Avg Bandwidth=32.3 802.11n Atheros Default Avg Transfer= 36.6 Avg Bandwidth=30.6 scenario 2: node 1 to node 2 node1-----wireless_link-----AP-----wired_link-----node2 802.11n Felix's Minstrel Avg Transfer= 83.4 Avg Bandwidth=69.8 802.11n Atheros Default Avg Transfer= 95.2 Avg Bandwidth=79.8 Overall, the results look pretty good. I am much more interested in results in scenario 1 but I am going to take a look at scenario 2 again. Let me know if I can help you test any other scenarios.
